Hey, folks! I feel compelled to share this. For the past several months, I've been aware of a strange rolling and rattling sound when I tip my right floorstander forward and back. Until tonight, I was hesitant to do anything because I didn't want to work on the speaker myself. Well, I finally took the initiative and removed the woofer so I could reach in and investigate. To my astonishment (and amusement), I extracted four (!!) foosballs from the bottom of the cabinet. My little cousins (4 and 6) love to play in the basement and I must have carelessly left the grill off one day. I was wondering where those balls went! Apparently, Paradigm's grills are effective not only in smoothing the sound but also in keeping little hands out of the bass port!
